Appi-ieation iiiea May aaien. seriai No. 715,276.

My invention relates particularly to planers for large and 'heavy Work,jsuc'h as are known as frog andsWitCh planers, in which the tools arefed to theY Work by hand.

The object of the'invention is to pro-y vde novel and improvedmechanism, ,Whereby motion may be imparted at will to either or both ofthe tool holders byhand or by power, in accordance with the wish of theoperator.y g Y y The invention" consists kof that certain novelconstruction and arrangement ofparts to beherei'nafter more particularlypointed outand claimed, in which the aboveresuits are attained. i

Figure@ is a perspective view of the rapid l traverse control mechanismseparated from the other parts, and without the supporting bearings. l fn Referring to the drawings, 1 and 2 are tools clamped to tool holding`members of the usual formwhich are fastened to slides 3 and 4 which areslidably Vgibbed to lvertical guides formed on tlieiront suriaces etsaddles 5 and. Saddles 5 and 6 are yslidably gibbed to rail `7. To theback ot saddle 5 is iiXed a nut, not shown, into which threaded railscrew 8, which is a long;

'Io feed rod 11 is slidably k iedfa similar planer provided with` thisinechf bevel gear driving a similar train of mecha- -nisni givingvertical motion to. slide 4. It ywill be seen that by rotating railscrew 8 horizontal motion` will be given totool l,` the direction ofhorizontal motion depending on the direction of rotation of the rail'screw. iiiotionwillbe imparted to tool 1, the direction of verticalmotion dependiii'gron the direction ofrotation yof* thefeed'rod. Simi;y

larly rotating rail screw 9 and feed rod 'l1 kwill impart motion to tool2. Thek various vparts so far mentioned may be of the design By rotating.feed rod 10, vertical l commonly used for such parts for ,plaiie`rs, f

or of any otherk suitable design, Aanddo ynot require ifurtherillustration or description.

The mechanism so far described differs from that usually Vemployed inthe following' particular only. Hitherto only one feed rod has beenemployed and the vertical move-V nient for both tools has been impartedby. this feed rod. Thishasfiiecessitatedl the use oif mechanism in eachhead for engaging and disengaging the vertical :Eeediso thaty the toolscould be moved vertically "either iiidependently or simultaneously.rllie usey ot separate feed rods in the manner described, avoids thisrcomplicationJ eachver'ticalfeed mechanism being permanently. geared. toits feed rod. y Referring now 'to Figure el.. the flic-ed rod shown `isrepresentative koiZ both 'feed rrods and both rail screwsieach of whichhas, at

theend nearest the operator, hereinafter termed the right hand end,those parts hereiiiafter described which are concentric with it.

On the right hand end of each rail screw or feed rod is i clutch' 12.To' the left of clutch 12 and iu crewed and pinned driven a counterboredhole in vrail 7, isball thrust bearing 13.y Concentiic iviththe railscrew or feed rod, and to the right/of clutch 12,y are bronze sleeve13a, spring lil, and washer 15. To the right of washer 15, and pinnedto` the rail screw yor feed rod, is bronze sleeve 'Y the rail screw vorfeed rod ris driving clutch 21 having clutch teeth 21 adapted to engageclutch teeth 12a on driven clutch 12;y This 1.6. The end of the railscrew orL feed rod iio driving clutch is ordinarily held out ofengagement by spring 14 acting against washer 15, which in turn pressesagainst an internal shoulder 21b formed in driving clutch The distancebetween shoulder 2lb and the end 21c of clutch 21 is slightly less thanthe length of sleeve 16, so that clutch 21 can turn freely, beingmachined to a running tit on bronze sleeves 13 and 16. wWhen clutch 21is moved to the left in order to engage clutch 12, it pushes washer 15over, compressing spring 14. ils soon as the pressure is relased, spring14 acts to return clutch 21 to the position shown.

Cn the outer rim of driving clutch 21 are former ger r teeth 21d bymeans of which thcv clutch is revolved. Cn the outer surface of theclutch are mounted spring 22 and ball thrust bearing 23. The spring ismaintained in a partially compressed position by sleeve 24, which isfastened to clutch 21 by screw 25. Acting against ball bearing 23 is aforked clutch shifter 26. When this shifter is moved so as to push ballbearing 2S to the left, clutch 21 is caused to move to the posi tion oftooth engagement. In case the tops of the clutch teeth come together sothat clutch can not engage, spring 22 will be compressed. Spring 22being much stiffer than spring 14, as soon as the driving clutch hasrot-ated suficiently to bring its teeth opposite the spaces of thedriven clutch, spring 22 will force clutch 21 into engagement, againstthe action of spring 14.

Clutch shifter 26 is pinned to shaft 2T having bearings in plate 18,which forms the end of the case on the rail, and plate 28, which formsthe front of the case on the rail. To shaft- 27 is pinned lever orhandle 29, to which is securely fixed detent 30 and knob 31. Then handle29 is pulled down, this detent is engaged by latch 32, and clutchshifter 26 is moved to the left, causing clutch 21 to engage clutch 12.Latch 32 is held in place by flat spring 33, and is pivoted at its upperend on pin 32 fixed in plate 2S. rlie latch is formed with aA button 32on its lower end so that it may readily be pressed back by the thumb ofthe operator. Then this button is pressed back the detent is released,spring 14 pushes clutch 21 to the right, carrying with it spring 22 andball thrust bearing 23, forcing over shifter 26, revolving shaft 27, andraising` handle 29 and detent 30 tothe position :shown in Figure 35.

Each of the -two rail screws and each of thel two feed rods is providedwith the associated clutches, sleeves, springs, bearings, clutchshifters, clutch shifter shafts, handles, detents, and latches describedabove, so that at will, each rail screw or feed rod may be coupled toits corresponding driving clutch. There are therefore, four of each ofthe above mentioned parts.

The gear teeth of the four driving clutches 21 mesh together so that theclutches are compelled to revolve together. Meshing with the teeth 21don one of the driving' clutches are teeth 34C formed on the outersurface of shiftable clutch 34, which is loose on, and concentric withshaft 35, the inneil end of which is journaled in the end of the rail,while the outer end is supported by radial thrust bearing 36, housed inbushing 23'?, which is fastened to plate. 18 by screw S18. Cn the end ofshaft 35 is keyed gear 39, which meshes with gear 40, keyed to shaft 41,which is manually rotatable by crank To reducefriction, shaft 41 ismounted on ball bearings 43, which are housed in gear cover 44, which isbolted to plate 18. Cn shaft 35 is mounted mechanically rotatable clutch45 having teeth on its outer rim, by which it is driven by gear 46,which in turn is driven by a` motor through a. suitable train ofmechanism to be described later.

Clutch 45 is provided with clutch teeth 45, adapted to engage clutchteeth, 34 formed on shiftable clutch 34. On shaft 35, and concentrictherewith, is mounted bronze sleeve 4T, having shoulder 47, againstwhich washer 48 is pressed by spring 49, which is held in place bybronze sleeve 50, fastened to sleeve 47 by screw 51. Shoulder 47, sleeve50, and washer 4S thus maintain spring` 49 in partial compression.Washer 4S presses against an internal shoulder 34" formed in shiftableclutch 34, which may be caused to shift axially on bronze sleeves 4'?and 50. To the right of shiftable clutch 34 is manually rotatable clutch52, which is pinned to shaft 35. Normally clutch teeth formed on theright hand end of clutch 34, engage clutch teeth formed on clutch 52,the clutches being held in engagement by spring 49. Consequently whencrank 42 is manually rotated, shaft 41, gear 40, gear 39, shaft 35,clutch 52, and shiftable clutch 34, and the four meshing drivingclutches 21, are all caused to rotate.

Should each of the driving clutches be in the position shown in Figure4, they will revolve freely upon sleeves 13L and 1G and neither of therail screws or feed rods will turn. Should, however, the operator pulldown one of the handles 29, as for instance the one associated with railscrew 8, the corresponding clutch 21 will be caused to engage its clutch12, and rail screw 8 will thereby be caused to rotate, moving tool 1 ina horizontal direction. Similarly by pulling down the handle 29associated with rail screw 9, this screw will be rotatably coupled tothe revolving mechanism, and tool 2 will thereby be caused to move in ahorizontal direction. By pressing the buttons 32EL formed on the lowerends of the latches 82, the latches will be disengaged from the detents30 on handles 29, which will permit the clutchs to reing the controllerdrum to its neutral position and disconnecting the motor from its sourceof energy. A movement of handle 82 to the opposite side of its neutralposition will again couple clutch 34; with clutch gear 45 and move lever7la to the opposite side of its neutral position so that controller 'T1will so energize the motor as to cause it to rotate in the oppositedirection. It will thus be seen that when handle 82 is in its neutral ormid position, motor G2 will stand still and the screws or rods vill beoperatively connected to handle for manual operation. A movement oflever S2 will disengage the mechanism from hand lever 4i, and opearte itby means of the motor (i2, the direction of motion being controlled bythe direction of motion of handle It will be seen that the inventionprovides an extremely convenient means for moving the two tools into anydesired position. that they may be moved independently orsimultaneously, and that the movement may be effected by hand or bypower. Also no attention is required from the operator except todetermine which tool he wishes to move, which direction he wishes tomove it. and whether he wishes to move it by hand or by power. Themechanism itself is so arranged that all of the necessary actions areaccomplished by a single movement, and the operators attention is notrequired for such matters as shifting clutches, throwing switches,disengaging feeds, or other similar actions.

It will be apparent that the mechanism may be changed in detail withoutaffecting the general principles upon which its action depends. I,therefore, do not wish to confine the invention to the exact form shown.but to include all those forms falling within the scope of the appendedclaims.
